4.3.8 - Social psychological explanations of aggression

Frustration and aggression

An outburst after disappointment, a copied threat and abusive crowd chanting may look similar, yet the explanation can differ. Frustration-aggression focuses on blocked goals, social learning on acquired responses, and de-individuation on self-awareness and accountability.

Dollard, Doob, Miller, Mowrer and Sears (1939) argued that frustration builds up as a psychological drive, rather like hunger or thirst. If a person is blocked from achieving a goal, the aggressive drive seeks release. The release of this drive is called catharsis.

The theory also explains why aggression is not always aimed at the person or object that caused the frustration. Sometimes the real source is too powerful, absent or abstract. A student who is furious about an exam grade may not shout at the teacher, because the teacher has authority. Instead, the student may go home and shout at a younger sibling.

Geen (1968) tested the effect of frustration in a laboratory experiment with male university students. Participants completed a jigsaw puzzle under different frustrating conditions: the puzzle was impossible, a confederate interfered so they ran out of time, or a confederate insulted them. Participants then had the opportunity to give the confederate electric shocks. The insulted group gave the strongest shocks, followed by the interference group, then the impossible-task group. All frustrated groups gave stronger shocks than a non-frustrated control group. This supports the idea that frustration can increase aggression, but it also shows that the meaning of the frustration matters: a personal insult produced more aggression than a merely difficult task.

Leonard Berkowitz later revised the theory. He argued that frustration creates a readiness for aggression rather than automatically causing aggression. Whether the person aggresses depends partly on aggressive cues in the environment.

Berkowitz and LePage (1967) used a laboratory shock task. Participants were angered by receiving shocks from a confederate and then could shock the confederate in return. When guns were visible nearby, angered participants gave more shocks than when no guns were present. This supports Berkowitz's claim that aggressive cues can lower the threshold for aggression. AQA answers should keep the dates separate: the weapon-effect study is Berkowitz and LePage (1967), while Berkowitz's broader reformulation is usually linked to 1989.

AO2 example: Priya has spent weeks preparing for a driving test but fails because she believes the examiner was unfair. She cannot safely confront the examiner, so later she snaps at her younger brother for a minor mistake. The frustration-aggression hypothesis explains Priya's aggression as displacement: the blocked goal created an aggressive drive, and the aggression was redirected onto a safer target.

Evaluating frustration-aggression

The frustration-aggression hypothesis is useful because it explains common everyday aggression: people often do become hostile when goals are blocked, especially if the block feels unfair. It also gives exam answers a clear chain: frustration, aggressive drive, possible displacement, and possible catharsis.

AO3 strength: displaced aggression has research support. Marcus-Newhall et al. (2000) carried out a meta-analysis of 49 studies of displaced aggression. Across studies, people who had been provoked but could not retaliate directly were more likely to aggress against an innocent third party than non-provoked participants. This supports a central part of Dollard et al.'s account: frustration can be redirected when direct aggression is blocked.

AO3 strength: Berkowitz makes the theory more realistic. The original claim that frustration always leads to aggression is too rigid. Berkowitz's reformulation is more flexible because it says frustration creates negative affect and readiness for aggression, but cues, appraisal and context influence whether aggression occurs. This explains why a frustrated person might lash out in one situation but withdraw, cry, problem-solve or seek support in another.

AO3 limitation: catharsis is not well supported. Bushman (2002) angered participants and then put them into a rumination punching-bag condition, a distraction punching-bag condition, or a no-punching-bag control. Participants who hit the punching bag while thinking about the person who angered them felt angrier and behaved more aggressively afterwards; doing nothing was more effective than venting. This challenges Dollard et al.'s assumption that releasing aggression reduces the aggressive drive.

AO3 limitation: cognitive appraisal matters. Dill and Anderson (1995) found that unjustified frustration produced more hostile aggression than justified frustration. This suggests that aggression depends not just on a blocked goal but on how the person interprets the block. Being delayed because someone is careless may provoke more aggression than being delayed because of a genuine emergency.

AO3 limitation: the original theory is environmentally deterministic. The original version makes aggression sound automatic: frustration causes aggression in a simple stimulus-response chain. A better answer is less deterministic. It recognises personal responsibility, individual differences, social norms, previous learning and biological factors. Frustration is one risk factor, not a complete explanation of all human aggression.

Real-world application: Berkowitz and LePage's weapon effect is often linked to debates about gun availability. The careful point is not "guns force people to be violent". The exam-useful point is subtler: aggressive cues may prime aggressive thoughts and increase aggression in people who are already angry, so environmental design and weapon visibility can matter.

Social learning theory and aggression

Social learning theory explains aggression as learned from other people. It does not have to deny biology. Its specific claim is that the form aggression takes - swearing, hitting, threatening, online flaming, using particular insults or solving conflict through violence - can be acquired through social experience.

A child can learn aggression directly. If they snatch a toy and keep it, aggression has been positively reinforced. However, Bandura argued that much human aggression is learned indirectly. Children observe role models such as parents, siblings, peers, influencers, film characters or game streamers. If those models are rewarded, admired or not punished, the observer is more likely to imitate.

A person can acquire an aggressive response without immediately performing it: learning and performance are different. Whether it is later enacted depends on motivation and expected consequences. Observational learning does not mean automatic copying. Bandura identified four mediational processes:

Self-efficacy helps explain why aggression can become part of a person's behavioural style. If a child repeatedly uses threats to get what they want, they may learn both that aggression works and that they are good at using it.
